Abstract

Objective: Disease recurrence, particularly intravesical recurrence (IVR) after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC), is common. We investigated whether violations of onco-surgical principles before or during RNU, collectively referred to as surgical violation (SV), were associated with survival outcomes. 

Material and methods: Data from a consecutive series of patients who underwent RNU for UTUC 2001–2012 at Skåne University Hospital Lund/Malmö were collected. Preoperative insertion of a nephrostomy tube, opening the urinary tract during surgery or refraining from excising the distal ureter were considered as SVs. Survival outcomes in patients with and without SV (IVR-free [IVRFS], disease-specific [DSS] and overall survival [OS]) were assessed using multivariate Cox regression analyses (adjusted for tumour stage group, prior or concomitant bladder cancer, comorbidity and preoperative urinary cytology).

Results: Of 150 patients, 47 (31%) were subjected to at least one SV. Overall, SV was not associated with IVRFS (HR 0.81, 95% CI 0.4–1.6) but with worse DSS (HR 1.9, 95% CI 1.03–3.7) and OS (HR 1.9, 95% CI 1.2–3) in multivariable analysis. Additional analyses with a broader definition of SV including also preoperative instrumentation of the upper urinary tract (ureteroscopy and/or double J stenting) showed similar outcomes for DSS (HR 2.1, 95% CI 1.1–4.3).

Conclusion: Worse survival outcomes, despite no difference in IVR, for patients that were subjected to the violation of sound onco-surgical principles before or during RNU for UTUC strengthen the notion that adhering to such principles is a cornerstone in upper tract urothelial cancer surgery.
